python interpreter binary for x86 android

[Jian Sun]

Hi there,

I would like to use the python interpreter bundled by the crystax-ndk directly on an x86-based Android device. Could someone tell me where can I find the prebuilt binary?

Thanks!

Sun

Hello,

Look to the folder $NDK/sources/python/$PYTHON_VERSION/shared/$ABI (for example, $NDK/sources/python/3.5/shared/armeabi-v7a). You'd find there python binary (python.bin), tiny shell wrapper (python), main library (libs/libpython3.5m.so), python modules (modules) and zipped python standard library (stdlib.zip).

Thanks! However I got the following error when trying to execute the python wrapper:

127|root@generic_x86:/data/python/x86 # ./python

error: only position independent executables (PIE) are supported.

I am using an emulator with Android 6.0 API level 23.

It looks like we need to have -fPIE and -pie flags set when building python? Does it mean the prebuilt python won't work for Android 5.0 and above?

Okay I need to learn to search harder :)

Apparently this has been fixed a month ago https://tracker.crystax.net/issues/1486

Downloading the build and trying...

[Jian Sun]

This is what I tried and observed:

1. I pushed everything from sources\python\3.5\shared\x86 to device. Did chmod a+x.

2. When I execute ./python, it complains unable to find libcrystax.so

3. I pushed libcrystax.so from sources\crystax\libs\x86 to the python libs directory (side by side with libpython3.5m.so)

4. ./python now gives segmentation fault.

Anything I am missing here?
